1 <br /> r <br /> Evaluating the Groundwater Flow Direction and Gradient <br /> 1 <br /> The elevations and positions (Y' and "y" lateral coordinates) of the monitoring well were surveyed <br /> by a licensed land surveyor The elevations of the monitoring wells were referenced to within <br /> 0 01 foot of the bench mark The horizontal distances were measured to the nearest 0 1 foot The <br /> elevations were taken to either the notch or the arrow on the well casing <br /> r' <br /> The groundwater elevations for each monitoring well were calculated by subtracting the depth to <br /> water from the wellhead elevation The groundwater elevation information was to construct a <br /> potentiometric surface map, which was used to evaluate the direction of groundwater flow and the <br />' magnitude of the groundwater gradient <br /> r <br /> r <br /> 1 <br /> 1 <br /> r <br /> r <br /> r <br /> r <br /> N lsacDMO031Prj18801880039IA 3ag doc Shaw Environmental,Inc <br /> B-2 <br />
